A wise professor of mine was once asking around for advice about filming people. A technician told him that the most important piece of equipment he should make sure to buy, the one thing that would make everything more professional, was none other than a good microphone. A good microphone produces such clear sound that it tricks us into thinking that the quality of the video is better, while a bad one can make any video seem amateur. People of the theatre world, I would like to let you in on a little secret: fight choreography is our microphone."
